How to Make Keto Zucchini Pizza Casserole
Step 1: Prepare the Base
Preheat your oven to 400 degrees. In a mixing bowl, combine the shredded zucchini, grated parmesan cheese, and eggs. Season with salt and pepper to taste. Press this mixture into the bottom of a well-greased 9×13 baking dish. This base layer gives your casserole structure while infusing those yummy zucchini flavors right from the start.
Step 2: Bake the Base
Pop that baking dish into the oven and let it bake for about 20 minutes. Baking first ensures that your zucchini base sets nicely before adding all those delicious toppings.
Step 3: Cook the Ground Beef
While your base is baking, heat a skillet over medium-high heat and add the ground beef. Brown the meat until it’s completely cooked through. This step adds rich flavor and texture to your casserole.
Step 4: Season It Up
Once browned, mix in Italian seasoning, minced garlic, salt, and pepper. Sauté this mixture for about 30 seconds—this helps release all those aromatic flavors that will make your kitchen smell incredible!
Step 5: Add Marinara Sauce
Reduce the heat to medium-low and pour in the low-carb marinara sauce. Stir everything together until well combined. Spreading this flavorful meat sauce over your baked zucchini base will elevate every bite of your casserole.
Step 6: Assemble Your Casserole
Carefully spread the meat sauce over the zucchini base you’ve prepared. Then sprinkle on that glorious shredded mozzarella cheese! Layer on sliced red onion, green bell peppers, turkey pepperoni slices, and black olives on top—this is where you can really personalize your dish.
Step 7: Final Bake
Return your assembled casserole to the oven and bake for another 10-15 minutes until everything is bubbly and golden brown on top. The anticipation will be worth it when you smell that deliciousness filling your home!
Now you’re ready to serve up hearty portions of Keto Zucchini Pizza Casserole to friends and family alike. Enjoy every cheesy bite!
